Ask HN: How to be a good bash script writer?
Assume elementary knowledge - pipes, redirection, awk/sed/cut/standard Unix tools.
How does one get to writing scripts that are -
(a) portable
(b) easy to debug
(c) clean and easy to modify
Where can I find good sample scripts?

You might like the Advanced Bash Scripting Guide. To quote:
"This tutorial assumes no previous knowledge of scripting or programming, yet progresses rapidly toward an intermediate/advanced level of instruction... It serves as a textbook, a manual for self-study, and as a reference and source of knowledge on shell scripting techniques"
